HMS Santa Monica was originally a Spanish frigate built in 1777 in Cartagena, Spain, and launched as Santa Ammonica. The vessel was a notable example of late 18th-century naval architecture, with a burden of approximately 956 long tons (971 tonnes). Although specific details about her dimensions and armament prior to capture are not provided, she was a 28-gun frigate at the time of her engagement with the British Royal Navy. The ship gained historical significance following her capture during a naval confrontation off the Azores in September 1779. On 14 September 1779, HMS Pearl, a British 14-gun sloop, engaged Santa Monica in a fierce battle that lasted about three and a half hours. The Spanish frigate, larger than Pearl, was eventually forced to surrender after a two-hour engagement. Casualties were substantial, with 38 men killed and 45 wounded on Santa Monica, while Pearl suffered 12 killed and 19 wounded. Despite her larger size, Santa Monica was not as heavily armed as her British counterpart and was rerated as a 36-gun frigate upon her incorporation into the Royal Navy. Following her capture, HMS Santa Monica served briefly under the British flag. However, her service was marred by internal unrest; a mutiny occurred aboard her on 16 July 1781. Her operational history ended when she was grounded off Tortola in the British Virgin Islands on 1 April 1782. The vessel was subsequently broken up, and her wreck was discovered in the vicinity of Coral Bay, off Saint John in what is now the U.S. Virgin Islands. The wreck was listed on the National Register of Historic Places in 1978, although its exact location remains undisclosed. The vessel’s history reflects the turbulent naval conflicts of the late 18th century and highlights the strategic importance of Caribbean waters during this period.
